7.7) Diagnostics and signals
A few devices issue special signals that allow you to recognize the
operating status or possible malfunctions.
7.6) Troubleshooting
The table 17 contains instructions to help you solve malfunctions
or errors that may occur during the installation stage or in case of
failure.

Symptoms
Recommended checks
The radio transmitter does not control the gate
and the LED on the transmitter does not light up
The radio transmitter does not control the gate
but the LED on the transmitter lights up
No manoeuvre starts and the “BLUEBUS” LED
does not flash
No manoeuvre starts and the flashing light is off
No manoeuvre starts and the flashing light
flashes a few times
The manoeuvre starts but it is immediately fol-
lowed by a reverse run
The manoeuvre is carried out but the flashing
light does not work
The manoeuvre is carried out but the Open
Gate Indicator does not work
Check to see if the transmitter batteries are exhausted, if necessary replace them
Check to see if the transmitter has been memorised correctly in the radio receiver
Check that ROBUS is powered by a 230V mains supply.
Check to see if the fuses are blown; if necessary, identify the reason for the failure and
then replace the fuses with others having the same current rating and characteristics.
Make sure that the command is actually received. If the command reaches the STEP-
BY-STEP input, the corresponding “STEP-BY-STEP” LED must light up; if you are
using the radio transmitter, the “BLUEBUS” LED must make two quick flashes.
Count the flashes and check the corresponding value in table 19
The selected force could be too low for this type of gate. Check to see whether there
are any obstacles; if necessary increase the force
Make sure that there is voltage on the flashing light’s FLASH terminal during the
manoeuvre (being intermittent, the voltage value is not important: approximately
10-30Vdc); if there is voltage, the problem is due to the lamp; in this case replace the
lamp with one having the same characteristics; if there is no voltage, there may have
been an overload on the FLASH output. Check that the cable has not short-circuited.
Check the type of function programmed for the S.C.A. output (Table 7)
When the light should be on, check there is voltage on the S.C.A. terminal (approximately
24Vdc). If there is voltage, then the problem will have been caused by the light, which will have
to be replaced with one with the same characteristics. If there is no voltage, there may have
been an overload on the S.C.A. output. Check that the cable has not short-circuited.

Wait for about 3s after which the LEDs corresponding to the manoeuvres in which the
defect occurred will light. The L1 LED indicates the result of the last manoeuvre
and L8 indicates the result of the 8th manoeuvre. If the LED is on, this means that a defect occurred
during that manoeuvre; if the LED is off, this means that no defect occurred during that manoeuvre.

7.6.1) Malfunctions archive
ROBUS allows the possible malfunctions that have occurred in the last 8 manoeuvres to be viewed; for example, the interruption of a mano-
euvre due to a photocell or sensitive edge cutting in. To verify the malfunctions list, proceed as in table 18.
